Sell supply zone reaction

Sell when price revisited for 2nd time on supply zone
I set SL above the previous high because i think the zone has been revisited before
but as your can see the result. Price move up and hit my SL before it moved down and reach my TP point

So. what l learn here is when you trade in small TF. You must have a proper SL and TP. and beware of slippage that might occur.
